The sustainability of ecosystem services depends on a firm understanding both how organisms provide these to humans and will be altered with changing climate. Unquestionably dominant feature most ecosystems, invertebrates affect many are also highly responsive climate change. However, there is still basic lack the direct indirect paths by which influence services, as well change those altering invertebrate populations. This indicates communication collaboration among scientists researching...
Abstract Effects of climate warming on wild populations organisms are expected to be greatest at higher latitudes, paralleling greater anticipated increases in temperature these regions. Yet, expectations assume that different regions equally susceptible the effects warming. This is unlikely case. Here, we develop a series predictive models for physiological thermal tolerances ants based current and future climates. We found tropical have lower tolerances, metric susceptibility warming, than...
Many studies have focused on the impacts of climate change biological assemblages, yet little is known about how interacts with other major anthropogenic influences biodiversity, such as habitat disturbance. Using a unique global database 1128 local ant we examined whether mediates effects disturbance assemblage structure at scale. Species richness and evenness were associated positively temperature, negatively However, interaction among precipitation shaped species evenness. The effect was...
Abstract Aim Using a standardized sampling protocol along 600‐km transect in northern Australia, we tested whether ant diversity within single biome, tropical savanna, decreases with increasing latitude (as surrogate of temperature) and decreasing rainfall, as is expected for biodiversity general. Location Northern Australia. Methods Ants were sampled using pitfall traps on three occasions at 1‐ha sand, loam clay sites each five locations the Australian Tropical Transect ( NATT ), from...
As cities become more populated and the density of urban development increases, local biodiversity is threatened. Urban greenspaces have capacity to preserve pollinator biodiversity, but quality support they provide depends on greenspace landscape attributes, including availability habitat foraging resources. Wild native bees important pollination services ecosystems, yet relatively little known about how management influences community composition diversity. Our study explores wild bee...
Abstract Aims Climatic change is expected to rearrange species assemblages and ultimately affect organism‐mediated ecosystem processes. We focus on identifying patterns relationships between common ant (representing 99% of total records) richness functional diversity; modelling how these may at local regional scales in future climatic conditions; interpreting changes might influence ant‐mediated Location Forested ecosystems eastern N orth A merica. Methods used a previously published dataset...
Summary Direct and indirect consequences of global warming on ecosystem functions processes mediated by invertebrates remain understudied but are likely to have major impacts ecosystems in the future. Among animals, taxonomically diverse, responsive temperature changes, play ecological roles which also respond changes. We used a mesocosm experiment evaluate two treatments (+3·5 +5 °C, set‐points) presence absence ant Formica subsericea (a mediator north temperate ecosystems) decomposition...
Abstract The relationship between levels of dominance and species richness is highly contentious, especially in ant communities. dominance‐impoverishment rule states that high only occur species‐poor communities, but there appear to be many cases diverse extent which dominant limit local through competitive exclusion remains unclear, such appears more apparent for non‐native rather than native species. Here we perform the first global analysis behavioral richness. We used data from 1,293...
What forces structure ecological assemblages? A key limitation to general insights about assemblage is the availability of data that are collected at a small spatial grain (local assemblages) and large extent (global coverage). Here, we present published unpublished from 51 ,388 ant abundance occurrence records more than 2,693 species 7,953 morphospecies local assemblages 4,212 locations around world. Ants were selected because they diverse abundant globally, comprise fraction animal biomass...
Insect mutualisms can have disproportionately large impacts on local arthropod and plant communities their responses to climatic change. The objective of this study was determine if the presence insect affects host herbivore warming. Using open‐top warming chambers at Harvard Forest, Massachusetts, USA, we manipulated temperature ants Chaitophorus populicola aphids Populus tremuloides plants monitored ant attendance persistence C. , predator abundance, stress, abundance Myzus persicae a pest...
No Mow May is a community science initiative popularized in recent years that encourages property owners to limit their lawn mowing practices during the month of May. The goal provide early season foraging resources for pollinators emerge spring, especially urban landscapes when few floral are available. We worked with city council Appleton, Wisconsin, USA. allow take place 2020. Four hundred and thirty-five registered Appleton. measured bee richness abundance yards subset homes (N = 20)...
Abstract We use observed patterns of species richness and composition ant communities along a 1000 mm rainfall gradient in northern Australian savanna to assess the accuracy turnover predictions derived from stacked distribution models (S‐ SDM s) constrained by macroecological ( MEM s). systematically sampled ants at 15 sites 50 km intervals 2012 2013. Using data, we created s richness, turnover. built for 135 using data museum collections online databases. compared two approaches stacking...
Abstract The increase in species diversity from temperate to tropical regions is one of the most widespread patterns biogeography. As humans continue drastically modify natural habitats, land‐use changes such as development cities could potentially alter typical latitudinal gradients. Cities depress or enhance biodiversity through filtering, localised extirpations, increasing niche availability, respectively. To address these possibilities and consequences for gradient, we constructed a...
Studies of species diversity patterns across regional environmental gradients seldom consider the impact habitat type on within-site (alpha) and between-site (beta) diversity. This study is designed to identify influence geographic space, local richness turnover ant in northeastern United States. Specifically, I aim 1) compare paired open forested transects variables that best correlate with richness; 2) document beta throughout region both habitat. systematically sampled ants at 67 sites...
Ecological studies often are subjected to unintentional biases, suggesting that improved research designs for hypothesis testing should be used. Double-blind ecological rare but necessary minimize sampling biases and omission errors, improve the reliability of research. We used a double-blind design evaluate associations between nests red wood ants ( Formica rufa , RWA) distribution tectonic faults. randomly sampled two regions in western Denmark map spatial RWA nests. then calculated nest...
